Patagonia Jacket, Fleece, and Outerwear Authentication Guide
→ See the Brand and Model Encyclopedia hereAuthentication Basics
Authenticating Patagonia products cannot be done by a single factor alone.
It is essential to comprehensively examine four points: tags, quality care tags, the mountain logo, and stitching.
Popular models (Retro-X, Down Sweater, etc.) are frequently counterfeited, so particular caution is advised.
⚠ Do not authenticate based solely on zippers or logos. Tags and quality care tags are paramount.
⚠️ Authentication criteria emphasized by RE-USE TOKYO
Tags (Age Consistency): Approx. 40% → Style number, country of manufacture, tag design, season notation
Quality Care Tag: Approx. 30% → Material composition, care instructions, accuracy of legal notations, consistency with main tag
Mountain Logo: Approx. 20% → Shape of Fitz Roy, embroidery quality, text placement, color usage
Stitching and Material Feel: Approx. 10% → Uniformity of stitches, fleece texture, fabric quality
※These are experienced-based guidelines, and authentication factors may vary by product.

⚠ Important Notes
Regarding popular models: Popular models like Retro-X, Down Sweater, and Nano Puff are frequently counterfeited. Authenticate with particular caution.
Regarding RN number: Patagonia's official RN number is "51884," and it is one of the important verification items. However, some products may not have an RN notation depending on the era or distribution region, so authentication cannot be based solely on the presence or absence of the RN number. Please judge comprehensively with other factors.
Regarding zippers: Patagonia has used multiple manufacturers and specifications for zippers, such as YKK and IDEAL, depending on the era. Authentication cannot be based solely on the zipper brand.
Regarding fleece quality: Genuine fleece (Synchilla, etc.) tends to be of high quality, but it cannot be judged solely by pile length. Some fakes may have long piles, and some genuine items may have shorter piles due to wear. Please judge comprehensively based on pile length, density, and softness.
Regarding products distributed in Korea: Patagonia generally uses common global specifications, but quality care tags and legal notations may differ depending on the country of distribution. Do not deem an item fake based solely on differences in tag specifications.
Regarding vintage items: Products from before the 1980s have significantly different tag specifications. Please authenticate after determining the era.
